Yellow nail syndrome--the triad of yellow nails, lymphedema and pleural effusions. A review of the literature and a case report.

The yellow nail syndrome, combination of yellow discoloured nails, lymphedema and pleural effusions, is a rare clinical condition. A review of the literature, including 97 patients, is presented. Most patients developed yellow nail syndrome in early middle age, and the overall male:female ratio was 1.1.6. The etiology of the syndrome is obscure, while the pathogenesis seems to involve impaired lymphatic drainage. A patient, whose recurrent pleural effusions were effectively controlled by chemical pleurodesis, is also presented.
